Camera tests: Battle of the 4.7-inch iPhones 6, 6s, and 7!

While I was shooting images for our all-shipping-iPhones camera test (SE, 6s, 6s Plus, 7, 7 Plus, and 7 Plus telephoto), I had quite a few people ask on Twitter about the iPhone 6. I didn't include it in our big test simply because it was too many iPhones to carry around NYC by myself — five was pushing it! — but I still wanted to give iPhone 6 owners an idea of how their shots might compare to the new 7 camera. So, without further delay, here's a quick test comparing all of Apple's 4.7-inch phones: I went through a variety of common shooting situations, as well as a section on color tests.

We're working on getting galleries to properly display in the iMore app and on RSS; until then, to properly view these photos, please visit our website.

How we tested

I shot with the iPhone 6, 6s, and 7 over the course of a few days using just the phones and the Camera app. The resulting photos haven't been touched up in any way — they're exactly the way the iPhone's image signal processor (ISP) made them, save for some image compression from uploading to our server.

Daylight

Our first major round of testing involved walking around a park and photographing scenery, as well as some portrait shots, selfies, and a cute dog or two.

Portrait

We started with a good old-fashioned outdoor portrait in bright — but not direct — sunlight. In general, you're not going to see a huge improvement from phone to phone when shooting in this kind of environment, save for some extra background detail: The iPhone has been great at shooting well-lit outdoor portraits for years, and this shoot was no exception.

All three phones put out nice photos here, though with slightly different color tones: The 6 tended to tint blue and over-saturated to mask lack of detail in the background, while the 6s and 7 have more reddish hues. The image signal processor on the iPhone 7 goes in almost the opposite direction of the 6, giving a much more desaturated and contrast-heavy look than either the 6 or 6s, though it appears to do so in order to capture more detail in the background. I tend to prefer the coloration of the 6s more here, but the level of detail on the 7.

Wide Portrait

Shooting portraits at a distance is where we start to see the iPhone 7 pull away. At small scale, these shots of me underneath a bridge (shot at a shutter speed of 1/30) look pretty similar, but when we blow up the photos, we start to get a very different impression.

At a 100% crop, the iPhone 7 again has a little less saturation than its 6 and 6s peers, but vastly more detail: You can see individual hairs and far more folds in the scarf and jacket, and the Apple Watch display is practically readable. This kind of extra detail may not matter much for your average Twitter or Facebook photograph, but it's hugely important for users who might want to blow up their photos for wallpaper, further editing, or printing.

Selfie

With the iPhone 7 sporting a newly-enlarged 7-megapixel sensor, it felt only right to shoot some outdoor selfies while we were at the park. The front-facing camera is one of the big photographic differences between the 6, 6s, and 7: The 6 sports a 1.2-megapixel sensor, while the 6s has a 5-megapixel option and the 7 has the aforementioned 7 megapixels.

The 6s and 7 are pretty close to each other in quality when it comes to bright light, but the 7 again offers a little bit more detail in the darker areas of the photo (under the collar of Rick's shirt and the trees in the background). The 6's 1.2-megapixel sensor just can't compete in terms of data — it renders the scene with a much more blue tint, and without the level of detail.

HDR

For our HDR shots, we tried to grab extra-tricky lighting with plenty of light and dark spots. Rick is practically backlit, here, with the sun shining in the upper left corner on a small pond and trees.

Given the very visible presence of the sun, all three of the images include lens flare, though the 6 bears the worst of it, with the 7 walking away with barely a few beams in the upper left corner of the picture. As with the portrait, the iPhone 7's ISP tends to process photos with more contrast than the other two smartphones, though that results in less light fuzz around the image, and clearer background details (like leaves in the pond), even though certain portions of the image are by nature darker than with the iPhone 6s.

HDR Landscape

This next shot is very similar to the one above, but we've removed the human subject in exchange for a nice landscape of differently shaped and colored greens, a brown road, and a grey border wall.

As with the other HDR image, the iPhone 7 escapes with the least amount of lens flare and refraction, and offers dark shadows without completely destroying detail (especially close to the light source). The 6 doesn't do too poorly here, though it can't quite capture the shadows with enough depth in comparison to the 6s and 7.

Landscape

For a wide landscape shot, we chose the riverbank: It not only had a wide variety of colors (blue sky, red bridge, green and yellow foliage, darker blue river), but also light variation.

You can really see the iPhone 7's f/1.8 aperture at work over the 6 and 6s's f/2.2 in the riverbank foliage: Despite shooting at a faster shutter speed (1/1200 vs 1/800 for the 6s and 1/1100 for the 6) than the other two smartphones — and thus, giving the sensor less time to get light — it has the greatest detail of all three photos, while avoiding the over-saturated blue skies and river of its predecessors. I'd always loved the iPhone's bright blue tint for clear skies, but it's somewhat more remarkable to see the sky exposed as it truly looked that day — with a softer, gentler blue.

Macro

We shot a lot of beautiful flowers and plants while wandering around the park, but this vine helped demonstrate another benefit of the iPhone 7's f/1.8 aperture: Shallower depth of field.

Though I do prefer the color tone and exposure of the iPhone 6s (thanks to its ISP exposing the scene at a shutter speed of 1/120th second in comparison to the 7 and 6's 1/60th), the soft optical blur on the background and light refractions through the trees provide for a more pleasing overall macro image. The 6 tries to get a nice background going, but it ends up looking more like camera shake than true optical blur.

Pets

What camera comparison is complete without gratuitous cute animals? Not this one. Outdoors and in great light — with little movement from our subject — all three iPhone models take great shots. You can see slightly more detail in the darker areas of the pup's fur with the 6s and 7, but overall, all of the cameras do well here.

Drinks

Better contrast, more light, nicer color tone: In a low-lit bar, the iPhone 7 captures a much clearer picture of the scene as-is thanks to its optical image stabilization and wider aperture. The 6s also offers a great photo, but it relies on a bit too dark of an exposure and an orange tint.

Colors

Though we can't currently embed the P3 Wide Color space for our iPhone 7 pictures, I still want to show off how each of the 4.7-inch iPhone models handles color.

This photo, of a red flower struck by direct sunlight, showcases both the 6s and 7 quite nicely. All three shot the flower at 1/120th second shutter speed, but received markedly different results in lighting: The 6 gets a beautifully deep red color on the flower, but underexposes the surrounding plants and overexposes the sky; the 6s finds a better balance between the flower and surrounding plants, but still blows out the sky; and the 7 chooses to go for a less-vibrant flower, but richer array of surrounding greens and a gorgeous depth of field. Though I do wish the 7's flower was redder, it's an easy post-production fix; trying to get the skies of the 6s and 6 photos to underexpose or add depth of field is a much more cumbersome task.

All three photographs of this yellow flower look great, though the 6s and 7 tend to prefer a warmer color tone and grab more detail on the petals and background.

This purple flower is the best in-nature example I found during our outdoor adventures to display the new wide color camera: Though the magenta hues found in both the 6 and 6s pictures are pretty enough, they're a fallacy: In reality, the flower is much closer to the iPhone 7's plum hue. Aside from the color variation, both the 6s and 7 get excellent macro shots here — even capturing a small spiderweb — and the 6 doesn't do too shabbily, either.

Again, all three cameras do pretty well at this outdoor macro shot, but the 7's ISP grabs the best auto-exposure (1/120, compared to the 6s's 1/150 and 6's 1/130) and most variety in colors.

Indoors

Inside we go! We alternated taking these shots in brightly- and poor-lit areas of the house, noted accordingly.

Portrait

Starting this challenge off on Hard mode, I snapped a photo of Rick and our two pups in a sunlit area. Though the dogs were mostly cooperative, the cameras still had to deal with slightly fidgety subjects and variegated light.

All three shots are pretty nice portraits, though the 6s and 7 deal with movement a bit better than the 6, and the iPhone 7 has more detail in darker areas of the pictures (see the bottom right, next to the dog's paw).

Selfie

When it came to indoor selfies, we shot three: Indoors in sunlight; indoors in low light, and indoors with a flash.

Both the well-lit and darker selfies show the improvements in Apple's front-facing sensor tech over the years: The iPhone 7 has the best detail for both shots, with better color metering and auto-exposure.

Flash

I feel like I should preface this section with my utter distaste for the awkwardness that is LED flash photography — even Apple's TrueTone technology can't make me love using a flash. But people take photos with it still, so a flash comparison I will do. (Under protest.)

The iPhone 6 looks like your traditional flash — brighter in some spots (like Rick's knees), darker in others. The 6s and 7 both expose equally, though in honesty, I prefer the color and light metering on the iPhone 6s here to the iPhone 7; in our tests, the iPhone 7 tended to lean more orange than the 6s's slightly blue tint, giving everything a slightly more sickly gleam.

Selfie flash is where I actually found myself pleasantly surprised: The improved Retina screen flash gives a pleasantly rosy glow to the scene without overexposing either Rick or myself. The 6s still does well, though the results leave us a little pale; the 6, of course, has no Retina flash, so this low-light selfie ends up blurry and very grainy.

Motion

To test indoor motion, we had Rick do a quick juggling test, which we shot in each iPhone's Burst mode, then picked our favorite shots.

Though the iPhone's shutter in indoor light isn't fast enough to catch a ball perfectly in motion, all three cameras do well at isolating the main subject while creating nice blurs of the juggling balls. The iPhone 7 offers the best overall detail and color grading in the scene, though the 6s isn't far behind, and the 6 still takes a pleasing picture (even if it doesn't quite get the colors in the room right).

Pets

For our final test, we had our two dogs pose in sunlit and dim areas of the house, respectively.

While all three pictures of our dog with her bone are cute, the iPhone 7 has the extra detail in the dark areas to really make the shot pop. (It's the only photo of the three that actually records detail in the pup's patchy eye.)

Similarly, this dark hallway shot of our dog highlights the iPhone 7's excellence in getting fine detail even without a ton of light. The 6 struggles with almost any motion in dim areas, opting instead to blur color and fur together; the 6s does a better job with movement, but still has trouble defining dark areas; and the 7 manages to get flecks of the dog's fur even in the darker underbelly areas.

Bottom line

If anything, these tests showed me concretely that Apple's cameras are aging well: The iPhone 6 and 6s can still take excellent photos, and you don't need the latest and greatest to compose a great shot. That said, the iPhone 7 offers subtle but important increases in detail for those who want to use their photos for non-Instagram endeavors, better depth of field thanks to the f/1.8 aperture, and wonderful low-light support.

The device's wide color profile may not seem like a huge improvement at present, but if you're shooting bright colors or want shots that are more true-to-life, that alone is a great reason to upgrade. And if you're a selfie-lover — especially if you're coming from the iPhone 6 — the jump from 1.2 megapixels to 7 is enormous (as is support for 1080p video recording, which we didn't showcase in this comparison, but I still find pretty darn cool).

For me, wide color, the f/1.8 aperture, and the first 4.7-inch iPhone with optical image stabilization in it were all the reasons I needed to jump from a 6s to a 7, but I'm also a tech junkie who's been snapping photos on the latest and greatest smartphones since 2005. The 6s is still an excellent camera, and if you need to wait a year due to finances or you're just not that impressed with the iPhone 7 as a whole, you're not going to destroy your Instagram following by doing so.

If you're on an iPhone 6, you could wait another year for next year's iPhone. But personally? I know I wouldn't.

Very nice shootout, thank you for doing this Serenity. I'm looking forward to the versions with the big phones, but this is awesome that you did this with the more common size of iPhones, the regular size.

HDR shots - on its own it might be fine, but I agree with a couple of other comments - the 6S looks more natural, the 7 looks like it's had some subtle Snapseed affect added to it.

The shot with the dog on the couch towards the end - I like the 7's better because you can see both eyes, but the trees outside the window are blown out.

Every. Single. Phone. that has attempted to do better with lower light over the years has had similar problems and tendencies. This goes from the LG G2 to the HTC One to the S7 and now the 7. There's only so much that can be done with these smaller sensors while attempting to balance out exposure and let in more light. The software has gotten really good at handling difficult situations, but trade-offs still exist. Major post-processing has to occur. The 6S, for me, is the perfect balance of keeping things realistic and high quality. The 7 is awesome, but some of those trade-offs are starting to creep in. The S7 is probably my favorite for the dark/light combo shots - its HDR is very very good. But besides that, I think I still prefer the 6S overall. But if you're coming from anything below the 6S, I'd do the 7 in a heartbeat!

Exactly what I do. I have an iPhone 6 and use that to take general shots, but if I want to capture something very nice, I use a DxO One. And increasingly (with the ability to take shots without being tethered to the phone), I use the DxO for almost everything.

It's been going on for the last year or so. On my android tablet, that I just sold a few months ago, it was working perfectly. Weird how on the iOS app does not continue properly, but on android it does.

Eh, Tests like these are ok for what the average person might see. If you really want to see the differences we need to know what you were focusing on, the camera not being locked down could mean camera shake not telling the whole story on sharpness and the exposure difference.

DP Review does those kinds of tests, and they're awesome, but most users don't care about how it performs in a clean room — they care about real-world "how does my camera focus when I grab it out of my bag and slide over on the lock screen" behavior. That's why we didn't lock focus and exposures, and instead let the phone's internal ISP do the metering so that we could see what the cameras get straight off the bat.

None of the photos are visible in the iMore app for iOS. I have to open your web version ( safari ) to view the pics. Pls fix this guys. With so many comparison articles coming up and pictures not visible at your app - you are forcing your readers to leave the app.

I'd have been happy to include the 6 Plus, but I don't actually have a working model in my bin of phones, and most folks were asking about the 6. (You'll see the 6s Plus in our upcoming all-model comparison, however.)

The 7 plus' primary camera is identical to the 7, the difference is it has a secondary camera, for now it's not being used for much outside of zoom and soon depth mapping. Though I'm sure many other advantages are in the pipe. This photo scenarios shown in this article would look identical on the 7 plus.

All iPhone 7 photos look like artificially sharpened with less tonal range (just my subjective perception without comparing the histograms). Especially the banding effect is visible on the face in the cropped photo. iPhone 6s photos look smoother and more natural.

It sure makes a difference which screen you view these photos on. I know that seem obvious, but they all looked the same on my iPad mini 2 with retina display. But, on my new MacBook One, the difference was apparent on nearly every photo. Overall, I think I like look of the iPhone 6s on every photo except for the selfie shots.

Agreed about how you are viewing. I am reading this on a big honking 4k monitor and the differences in the images are pretty stark for several of the shots.

The colors and low-light shots are what impress me with the iPhone7. I went from a 6 to an SE so I got a bump in quality, but I still end up using ProShot instead of the camera app when I want a really good picture (and I don't have my camera).
